He had a lot to learn in the first X-Men, so a lot was left to be desired. But the Mystique/Wolverine fight was pretty amazing. Well choreographed. And the way Mystique was crafted was just stunning. Her movements were crazy cool.

In X2, he took everything he learned from the first film and applied it. Every fight sequence or VFX sequence was golden. The opening Nightcrawler scene. Wolveriene vs Deathstrike. Wolverine during the mansion invasion. The tornado dogfight. Mystique infiltrating Strykers base. Jeans final scenes at the lake.
